2'0 all whom it may concern i Be it known that I, FERDINAND G. HENRY a citizen of the United States, residing at New York, in the county of New Yorkand State of New York, have invented certain new and useful Improvements in Shoe- Polishing Mechanisms; and I do hereby declare the following to; be a full, clear, and exact descriptionof the invention, such as will enable others skilled in theart to which 1 it appertains to make and use the same.

This invention relates to shoe, polishing machines and has foran object to provide a mechanism of the same general type as that disclosed inapplication 816,272, filed February 3rd, 1914, in the name of Charles F.

Burkhart with improved means for opera tion and improved means for carrying the polishingfabrio I g A further object of the invention is to provide an improved means for converting a rotary motion into an: oscillating motion transmitted to the polishing heads.

A further object of the invention is to provide an improved polishing head.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully de scribed and claimed. i

In the drawings: Figure 1 is a view of the device with parts of the housing broken away, the generalstructure being shown in perspective andthe polishing heads in oper ative position. Fig. 2 is a view of the devloe with the polishing heads, in inoperative positlon seen also in perspective. Flg.

Fig. 5 is a detail view in side, elevation of a fragment of the fabric holder. "Fig. 6 is a detailsec tional. view through the fabric holder and adjusting means. Fig. 7 isa detail view of the fabric holder in sideelevation. Fig. 8 is a perspective view of the mechanical movement employed to impart an oscillatingmovement to the polishing heads.

and lower between the and the inoperative position shown at Fig. 2. To raise and lower such heads the trunnions12 of the yoke 11 are provided with gears 13 which. engage nally by a cam 18 carried by a gear 19. I The gear 19 receives rotary motion from a worm 20 carried by a shaft 21 whichreceives motion from a .drivlngshaft 22 in anyapproved manner as by the pinion 23 and gear.

2 1 and the beveled gears 25. It is obvious I that as the shaft 21 rotates the worm 20 will tend to "rotate the cam" 18 which will raise and lower the rack 17 thereby oscillating the gears 14 which being interengaged with the gears 13 also oscillate the trunnions 12 and the yoke 11 therewithto raise the yoke from the position shown at Fig. 1 to the position shown at Fig. 2 or reverse. The yoke 11 also carries a housing 26 mounted to oscillate upon a shaft 27 which is in alinement with the axis of the trunnions 12. and

is provided with a beveled gear 28 taking motionfroni a gear 29 carried upon the shaft 21. It is obvious, therefore, that the yoke'll may be raised and lowered without affecting the engagement of the gears 28 and 29. The shaft 27 also carries a beveled gear 30 which engages a gear 31upon a shaft 32 which extends into a housing 33 forminga I part or an enlargement in the center ofthe yoke 11.

I The shaft 32 within the housing 33 is provided with a crank 34 carrying a pin 35 32 and transecting the axis of shafts 36 which are also journaled in the yoke 11. These shafts 36 carry a ring 37 rigidly connecting such shafts with the pin35 extending through such ring and embraced by a bearing block 38 which is also pivoted at c i positions shown at gs- 1 and 2 from the operative position shown at Fig. 1

disposed at an angle to the axis of the shaft 37 to suchring; It is obvious, especially I from an examination of Fig. 8 that the rotationof the shaft 32 will cause the pin 35 to describe two cones with their apices meetingat the'axisof the shafts 36 and that as said pin 35 rotates it will cause thefsaid ring 37 and shafts 36 to oscillate. 'The shafts 36 are provided with gears 40 engaging other gears 41 carried upon shafts 42 which carry the polishing heads 10. It

will be apparent, therefore,that as the shaft 21rotates it not only, serves to raise and lower the polishing heads at intervals deter-f mined by the cam 18 but also serves to oscillate the polishing heads upon their journals 12. Itis intended to drive the polishing heads only a certain period of time during the operation of the entire mechanism but the matter of intermittent drive forms no part of the present invention and so far as the present'invention is concerned the polishing heads will e lowered to operative position and oscillated during the greater portion of the revolution of the gear 19 and will be qiichly raised from such operative position as shown in Fig. 1 to inoperative position as shown at Fig. 2, such raising and lowering, however, not interfering in any way with the oscillation of such polishing heads.

The polishing heads themselves comprise a frame consisting of a cross-bar a8 and pins a l rigid with the bar 13 and arranged in parallelism. h ilounted upon such pins as are sleeves 15 rigidly and preferably integrally connected by a rib 4% and rotatable upon such pins a l. The sleeves 15 carry pins'ii rigidly secured thereto and extending from each of such pins A toward the other. Upon the pins 47 sleevesA-S are slidably mounted with springs t9 controlled by tension nuts 50 for exerting tension upon such sleeves as.

Hinged to the sleeves 48 are fabric 'carriers 51 which are similar to the fabric carriers disclosed in Patent 1,051,387, issued January 28, 1913, upon the application of Charles F. Burlrhart and comprise tubes slitted along their under sides as indicated at 52, curved downwardly as indicated at 58 and carrying the fabric 5 1 by means of a roll or other enlargement 55 formed integral with or separate from such fabric 5 1-, as best shown at Figs. 3, 4: and 6. The relation of the fabric 5 1 to the sleeves4i8 is such that the tension of the springs 49 serves to hold such fabric taut but to permit the sleeves 48 to slide on the pins 4:7 against the tension of such springs 49 to assume a curved position. Such curvature is permitted by the sleeves e5 moving rotatably upon the pins 1% as the fabric 54 is bulged to produce such curvature. The, fabric carriers 51 are pivoted to the sleeves 4:8 by means of ears 56 which also" carry adjusting screws 57, by the adjustment of which the sleeves 4E8 may be held at such distance from the sleeves a5 that the fabric 5 1 need not in inoperative position be taut but may assume any degree of looseness which is found desirable. i

In operation the shoe to be operated upon will be placed in such position that ,when the polishing heads are in the position shown at-Fig. 1 the fabric 5% will bear with opposite directions 7 the same time tilt the head tO'POllSll' not considerable tension upon the shoe and cause such fabric to assume an arcuate or bulged condition with the shoe within such are and when such polishing head oscillates upon its shaft 42 will draw the fabric alternately in 7 over the shoe and at only the top of the shoe but the sides as well.

t is obvious also that to polish over the curvature of the toe of the shoe it is necessary that the fabric be curved at that side for which purpose the fabr c holder 51 1s curved as at 53. It is also obvious that when the fabric holders 51 are tiltedto provide a bulge in the fabric the position and relation of the extremities 53 will be such as to produce a greater degree of looseness in the fabric at that edgethan at any other point. It is also obvious that the springs 49 may be adjusted by the use of the nuts 50 to apply. different degrees of tension to the opposite sides of the fabric as it is found necessary to apply greater frictional stress upon some parts than other parts of the shoe.

position to be engaged by the polishing heads in the position shown at Fig. 1 and with the heads themselves in inoperative position as shown at Fig. 2 when the device starts to operate it starts at once to descend" also obvious that by engaging the shoe when in oscillationit engages first at slight tension and the tension increases to complete operative tension and that the reverse is true when the polishing-head leaves the shoe, that is that it leaves the shoe while oscillating and reduces the frictional engagement so as not to leave the imprint of the fabric upon the polished surface of the shoe.
